Public hostname should be customizable in dashboard

public hostname should be customizable, not just from domains in account
For example:

then configure custom hostnames in Cloudflare for SaaS
Fallback Origin:
Custom Hostnames:

use localmanaged tunnel yaml like this

  - hostname:

then it works
but if i use dashboard, i can’t add public hostname because it’s not in my account

I’m also curious how to support tunnels using domains in different accounts.
